ZnCo2O4 Quantum Dots Anchored on Nitrogen‐Doped Carbon Nanotubes as Reversible Oxygen Reduction/Evolution Electrocatalysts

Abstract

ZnCo₂O₄ quantum dots anchored on nitrogen-doped carbon nanotubes (N-CNT) retain the high catalytic activity of ZnCo₂O₄ to oxidize water while enabling an efficient oxygen reduction performance thereby combining these desirable features. These advantages realize a bifunctional catalytic activity for ZnCo₂O₄/N-CNT that can be used in rechargeable zinc–air batteries.
